XF 1.5 Dumb newbie question about changing parts of pages color

Hi guys,
Former vBulletin user here. Just down loaded Xenforo and I'm loving it. I have a dumb question...
I'm trying to modify some of the colors on my site. Is there a diagram, or something, that shows the parts of a web page that match the names in the "style properties group"? I'm getting tired of having to change the color at my CP and the go to my website to see where I actually changed the color. In other words, something like a screen shot of a webpage and maybe an arrow to a particular part of the page (like tabs container) and the name Xenforo uses for that part of the page?
Sorry if this sounds vague and confusing.
Thanks in advance for any help.
Regards,
Rick
